BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates in general to medicament formulations andmethods for treating neoplasms, and, more particularly, to methods fortreating benign neoplasms, in situ neoplasms, malignant neoplasms,and/or neoplasms of uncertain or unknown behavior by administering anisothiocyanate functional compound augmented with a secondary,antineoplastic medicament to a patient having one or more neoplasms. Thepresent invention also relates to the prophylactic administration offormulations disclosed herein.

2. Background Art

Neoplasms are ubiquitous—many forms of which have no known effectivetreatment and/or cure, and most of the current treatments for neoplasms,including, but not limited to, malignant neoplasms or cancers arereplete with drawbacks, side effects, and/or toxicity issues.

It is therefore an object of the present invention to provide new,useful, and nonobvious medicament formulations and methods for treatingand/or preventing benign neoplasms, in situ neoplasms, malignantneoplasms, and/or neoplasms of uncertain or unknown behavior.

These and other objects of the present invention will become apparent inlight of the present specification, claims, and drawings.

SUMMARY OF THE INVENTION

The present invention is directed to a medicament formulation,comprising: (a) a first medicament, wherein the first medicamentpreferably comprises an isothiocyanate functional compound/surfactant;and (b) a second medicament, wherein the second medicament preferablycomprises an antineoplastic agent, such as a cytotoxic antineoplasticagent and/or a targeted antineoplastic agent. The therapeutic effectson, for example, malignant neoplasms are believed to be enhanced by thesynergistic effect of the two medicaments/active ingredients.

The present invention is also directed to a method for treating benignneoplasms, in situ neoplasms, malignant neoplasms, and/or neoplasms ofuncertain or unknown behavior, comprising the step of: administering toa patient (e.g., mammal/human) a first medicament, wherein the firstmedicament preferably comprises an isothiocyanate functionalcompound/surfactant, and a second medicament, wherein the secondmedicament preferably comprises secondary, antineoplasticmedicament—such as a cytotoxic antineoplastic agent and/or a targetedantineoplastic agent.

In a preferred embodiment of the present invention, the first and secondmedicaments are collectively and/or independently administered to thepatient orally, intravenously, intramuscularly, intrathecally,cutaneously, subcutaneously, transdermally, sublingually, buccally,rectally, vaginally, ocularly, otically, and/or nasally. In thisembodiment, the amount of isothiocyanate functional surfactantadministered to the patient preferably ranges from approximately 0.5nmol/cm2 to approximately 10 μmol/cm2 when topically administered.

In another preferred embodiment of the present invention, the weightratio of the first medicament to the second medicament is approximately1:1,000,000 to 1,000,000:1, 1:100,000 to 100,000:1, 1:10,000 to10,000:1, 1:1,000 to 1,000:1, 1:500 to 500:1, 1:100 to 100:1, 1:10 to10:1, and/or 1:1.

DETAILED DESCRIPTION OF THE INVENTION

While this invention is susceptible of embodiment in many differentforms, there is shown in the drawings and/or described herein in detailseveral specific embodiments with the understanding that the presentdisclosure is to be considered as an exemplification of the principlesof the invention and is not intended to limit the invention to theembodiments illustrated.

In accordance with the present invention, medicament formulations aredisclosed herein, comprising: (a) a first medicament, wherein the firstmedicament preferably comprises an isothiocyanate functionalcompound/surfactant; and (b) a second medicament, wherein the secondmedicament preferably comprises an antineoplastic agent, such as acytotoxic antineoplastic agent and/or a targeted antineoplastic agent.The medicament formulations of the present invention are used to treatand/or prevent, for example, benign neoplasms, in situ neoplasms,malignant neoplasms, and/or neoplasms of uncertain or unknown behavior.The therapeutic effects on, for example, malignant neoplasms or cancersare believed to be enhanced by the synergistic effect of the twomedicaments/active ingredients. In particular, and especially fortopical applications, the isothiocyanate functional compound/surfactant(i.e., the first medicament) permeates the skin and makes it easier forthe second medicament or other actives (e.g., tertiary medicament,etcetera) to penetrate the skin. Once the isothiocyanate functionalcompound/surfactant has intercalated with the lipid bilayers of thestratum corneum, this leads to a looser, more permeablestructure/environment. Unlike other presently available isothiocyanatecompounds, the isothiocyanate functional compounds of the presentinvention are surfactants—and many are advantageously C12 surfactantsand/or +/−C2. Therefore, it not only makes it easier for otherantineoplastic agents and/or cancer drugs to penetrate into the skin, italso contributes its own antineoplastic activity as an isothiocyanate,hence the synergism.

In one embodiment, the present invention is directed to a method fortreating and/or preventing benign neoplasms, in situ neoplasms,malignant neoplasms, and/or neoplasms of uncertain or unknown behavior,comprising the step of: administering to a patient (e.g., mammal/human)a first medicament, wherein the first medicament preferably comprises anisothiocyanate functional compound/surfactant, and a second medicament,wherein the second medicament preferably comprises secondary,antineoplastic medicament or other medicament. Preferably, theisothiocyanate functional surfactant comprises one or moreisothiocyanate functional groups associated with an aliphatic and/oraromatic carbon atom of the isothiocyanate functional surfactant. Itwill be understood that isothiocyanate functional surfactants,regardless of their ordinary meaning, are defined herein as a surfactanthaving an isothiocyanate functional group associated therewith. It willbe yet further understood that the term “associated” as used herein inchemical context, regardless of its ordinary meaning, is defined hereinas attached, a covalent bond, a polar covalent bond, an ionic bond, ahydrogen bond, van der Waals forces, electrostatic interaction, directlyand/or indirectly linked, etcetera.

The term surfactant derives from contraction of the termssurface-active-agent and is defined herein as a molecule and/or group ofmolecules which are able to modify the interfacial properties of theliquids (aqueous and non-aqueous) in which they are present. Thesurfactant properties of these molecules reside in their amphiphiliccharacter which stems from the fact that each surfactant molecule hasboth a hydrophilic moiety and a hydrophobic (or lipophilic) moiety, andthat the extent of each of these moieties is balanced so that atconcentrations at or below the critical micelle concentration (i.e.,CMC) they generally concentrate at the air-liquid interface andmaterially decrease the interfacial tension. For example, sodium saltsof saturated carboxylic acids are extremely soluble in water up to C8length and are thus not true surfactants. They become less soluble inwater from C9 up to C18 length, the domain of effective surfactants forthis class of compounds. The carboxylic acids (fatty acids) can beeither saturated or unsaturated starting from C16 chain lengths.

Without being bound by any one particular theory, it is believed thatthe isothiocyanate functional surfactants disclosed herein facilitatetreatment of neoplasms and/or neoplastic conditions by, elevating phaseII enzymes (e.g., HAD(P)H quinine oxidoreductase) which are believed to,among other things regulate inflammatory responses within the body.

In accordance with the present invention, the isothiocyanate functionalsurfactants may be used as an administered leave-on/leave-in product inwhich one or more surfactants remain on/in the body and are notimmediately and/or ever removed from the body. Alternatively, theisothiocyanate functional surfactants of the present invention may beused in an administer and remove fashion. For either case, it ispreferred that the isothiocyanate functional surfactants be generallymild to human body (e.g., non-irritating or low-irritating). Inparticular, anionic N-alkanoyl surfactants derived from amino acids areespecially preferred because, while not completely predictable, theyhave a tendency to be mild. The methods of preparation detailed in thisinvention employ, but are not limited to, amino acids that possess atleast two amine functionalities, at least one of which is converted toan N-alkanoyl functionality, and at least one of which is converted intoisothiocyanate functionality. The amino acids include, but are notlimited to, the α-amino acids lysine, ornithine, 2,4-diaminobutanoicacid, 2,3-diaminopropionic acid, 2,7-diaminoheptanoic acid, and2,8-diaminooctanoic acid. Additionally, amino acids other than α-aminoacids may be employed, such as β-amino acids, etcetera. It will beunderstood that amino acid derived surfactants are preferred due totheir mild nature, but any one of a number of other surfactants arelikewise contemplated for use in accordance with the present invention.

Methods for preparing isothiocyanate functional surfactants and/or theirprecursors can involve, but are not limited to, conversion of an aminefunctionality to an isothiocyanate functionality. The methods ofconversion of amine functionalities to isothiocyanate functionalitiesinclude, but are not limited to: (1) reaction with carbon disulfide toyield an intermediate dithiocarbamate, followed by reaction withethylchloroformate or its functional equivalent such asbis(trichloromethyl)-carbonate, trichloromethyl chloroformate, orphosgene; (2) reaction with thiophosgene; (3) reaction with1,1′-thiocarbonyldiimidizole; (4) reaction with phenylthiochloroformate;(5) reaction with ammonium or alkali metal thiocyanate to prepare anintermediate thiourea followed by cleaving to the isothiocyanate viaheating; and (6) reaction with an isothiocyanato acyl halide[SCN-(CH₂)_(n)-CO-Cl]. The resulting isothiocyanate functionalsurfactant, depending on the method of preparation, can be isolated as apure material or as a mixture with other surfactants. The resultingisothiocyanate functional surfactant, depending on the method ofpreparation, can be isolated and used directly in nonionic form, anionicform, cationic form, zwitterionic (amphoteric) form, and/or in a neutralsurfactant-precursor form in combination with a base such as sodiumhydroxide or triethanol amine if the neutral surfactant-precursor formpossesses a protonated carboxylic acid group such that reaction(deprotonation) with the base converts the neutral surfactant-precursorform to an anionic surfactant, or in neutral surfactant-precursor formin combination with an acid if the neutral surfactant-precursor formpossess amine functionality such that reaction (protonation) with theacid converts the neutral surfactant-precursor form to a cationicsurfactant.

In accordance with the present invention the step of administeringcomprises, but is not limited to, systemic administration, localinjection, regional injection, spraying, applying, dripping, dabbing,rubbing, blotting, dipping, and any combination thereof.

In one preferred embodiment of the present invention, the isothiocyanatefunctional surfactant is removed from body and/or affected area (e.g.,in, on, and/or proximate to a neoplasm) after a period of time. Such aperiod comprises, but is not limited to, seconds (e.g., 1 second, 2seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, 30 seconds, 45seconds, and 60 seconds), minutes (e.g., 1 minute, 2 minutes, 5 minutes,10 minutes, 15 minutes, 20 minutes, 30 minutes, 45 minutes, and 60minutes), hours (e.g., 1 hour, 2 hours, 4 hours, 5 hours, 8 hours, 10hours, 15 hours, 24 hours, 36 hours, 48 hours, and 60 hours), days(e.g., 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days,14 days, 21 days, 30 days), etcetera. It will be understood that thestep of removing preferably occurs via purging, rinsing, wiping, and/orextracting—just to name a few.

Depending upon the subject and/or the severity of the condition and/ordisease, multiple administrations may be necessary. As such, the stepsof administering and/or removing the isothiocyanate functionalsurfactant may be repeated one or a plurality of times.

EXAMPLE I Preparation of a mixture ofN_(α)-lauroyl-N_(ε)-isothiocyanato-L-Lysine withN_(g),N_(ε)-bis-lauroyl-L-lysine

A 1 liter beaker equipped with an overhead mechanical stainless steelpaddle stirrer was charged with 100 mL of 1 M NaOH (0.100 mol). Stirringwas begun and the beaker cooled to −5° C. to −10° C. using a salt/icebath. Next, 23.4 g (0.100 mol) of N_(ε)-benzylidene-L-lysine (preparedvia the method of Bezas, B and Zervas, L., JACS, 83, 1961, 719-722) wasadded. Immediately afterward and while keeping the solution cold, 140 mL(0.140 mol) of precooled (in a salt/ice bath) 1 M NaOH and 26.1 mL oflauroyl chloride was added in two equal portions over a period of 6minutes. The mixture was stirred for 10 more minutes at −5 to −10° C.,then the ice bath was removed and the reaction mixture allowed to stirfor another 1 hour while warming to room temperature. Next, the reactionmixture was cooled using a salt/ice bath and then sufficientconcentrated HCl was added to adjust the pH to 7.5-7.8. With the pH at7.8-7.8 and with continued cooling and stirring, 4.6 mL (60% ofstoichiometric, 0.068 mol) of thiophosgene was added drop-wise via anadditional funnel over the period of 1 hour. During this time,sufficient 1 M NaOH was added to maintain a pH range between 7.5-7.8.After the thiophosgene addition was complete, additional 1 M NaOH wasadded as necessary until the pH stabilized in 7.5-7.8 range. Next,sufficient 30% NaOH was added to adjust the pH to approximately 8.5.Next, 12 mL (0.051 mol) of lauroyl chloride was rapidly added, followedby sufficient 1 M NaOH to keep the pH in the range of 8.00-8.50. Next,sufficient concentrated HCl was added to adjust the pH to 1.5. Thereaction mixture was filtered via vacuum filtration, and the precipitatewashed with dilute HCl (pH=2). The product, a white moist solid, wasdried in vacuo while heating to 60° C. 45.19 g of white solid productwas recovered, a mixture of predominantlyN_(α)-lauroyl-N_(ε)-isothiocyanato-L-lysine and N_(α),N_(ε)-bis-lauroyl-L-lysine (determined via LC-MS analysis). Bothcompounds in this mixture can be simultaneously converted into anionic(carboxylate) surfactants via reaction with aqueous NaOH to yield aclear aqueous solution of the surfactants.

EXAMPLE II Preparation of PureN_(α)-lauroyl-N_(ε)-isothiocyanato-L-Lysine Step 1: Preparation ofN_(α)-lauroyl-N_(ε)-carbobenzoxy-L-Lysine

60.0 g of N_(ε)-cbz-L-Lysine (cbz is carbobenzoxy) purchased fromAtomole Scientific Company, LTD was added to a three-liter beaker alongwith 1200 mL of RO water and the mixture was stirred. Next, 39 mL of 30%aqueous NaOH was added, resulting in dissolution of theN_(ε)-cbz-L-Lysine. The resulting solution was cooled in an ice bath andthen 52.5 mL of lauroyl chloride was added. The ice bath was removed 30minutes later, and stirring continued for an additional six hours, atwhich time 18 mL of concentrated hydrochloric acid was added. Thereaction mixture was then filtered via vacuum filtration, the whitesolid product washed with 1 M aqueous HCl, and then the solid productwas dried in vacuo while heated to approximately 85° C. 96.5 g of drywhite solid product was obtained. The product can be further purified bydissolving it in methanol, filtering off any insoluble precipitate, andremoving the methanol in vacuo to recover a white solid product (mp99.5-103.0° C.)

Step 2: Preparation of N_(α)-lauroyl-N_(ε)-ammonium chloride-L-Lysine

10.0 g of N_(α)lauroyl-N_(ε)-carbobenzoxy-L-Lysine was weighed into aone liter Erlenmeyer flask equipped with a magnetic stir bar. 150 mL ofconcentrated hydrochloric acid was added and the solution was stirredand heated in an oil bath to 104° C., then allowed to cool with the oilbath back to room temperature. The solution was then cooled to 9° C. forapproximately four hours, during which time a large mass of whiteprecipitate formed. The reaction mixture was filtered in vacuo andrinsed with a small amount of cold 1 M HCl. The white solid reactionproduct was then dried in vacuo while being heated to 78° C., yielding7.89 g of white solid product (mp 191-193° C.).

Step 3: Preparation of N_(α)lauroyl-N_(ε)-isothiocyanato-L-Lysine

0.46 mL of thiophosgene was added to 30 mL of dichloromethane in a 125mL Erlenmeyer flask equipped with a magnetic stir bar. To this solutionwas drop wise added over 15 minutes a solution consisting of 2.00 gN_(α)lauroyl-N_(ε)-ammonium chloride-L-Lysine, 10 mL RO water, and 2.7mL 20% aqueous NaOH. Stirring was continued for an additional 30minutes, after which sufficient concentrated hydrochloric acid was addedto lower the pH to 1 as indicated by testing with pHydrion paper. Thereaction solution was then transferred into a separatory funnel and thebottom turbid dichloromethane layer was isolated and dried withanhydrous magnesium sulfate and gravity filtered. To the filtrate wasadded 50 mL of hexanes. The solution was then concentrated via removalof 34 mL of solvent via trap-to-trap distillation and then placed in a−19° C. freezer. A mass of white precipitate formed after a few hoursand was isolated via vacuum filtration and then dried in vacuo for 2hours. 1.130 g of a slightly off white solid powder product was obtained[mp 37.0-39.0° C.; IR (cm⁻¹), 3301sb, 2923s, 2852s, 2184m, 2099s, 1721s,1650s, 1531s, 1456m, 1416w, 1347m, 1216m, 1136w].
